Is it possible to softmod a wii v4.3 WITHOUT the game(batman, indiana jones)?

Is there any way to softmod a wii v4.3u without the game exploits. I know 4.2 is easy, but it seems 4.3 is a little more difficult. Is there any other way? The only games i have is the lego batman and star wars but they are backup copies! And without a softmodded wii, they are pretty much useless. So, is there any other way? Thanks much!
